24 Claims.

My invention'relates to certain improved devices used in conjunction with rotary printing presses, and more particularly relates to web printing presses and especially to web gravure presses printing from intaglio cylinders. The objects of my invention are,'among other things, to provide a novel and simplified type of rotary printing press in which the printing cylinder is both laterally adjustable in the press frames as well as reversibly rotatable, the frames being formed with laterally extending reentrant spaces on either side to permit such cylinder to be readily removed from, and likewise installed in, the frames from either end of the printing unit which arrangement has peculiar advantages in presses of. the gravure type.

A further featureof my invention is the provision of improved mechanism for lifting the printing cylinder from its bearings in the frames to permit the removal of the cylinder by running same off on pivoted runway bars, which mechanism may also be utilized in placing the cylinder in the press frames in printing relation in the unit. The reentrant spaces also allow for a ready exchange of printing cylinders which isan important advantage in rotary gravure presses.

A- further feature of my invention is the provision of a novel reversible clutch drive for the printing cylinder which is laterally slidable in the press frames to permit the cylinder to be rotated in either direction as well as to be readily removed or installed in thepress frames to suit printing requirements as hereinbefore described.

Further objects and advantages will appear hereinafter and be particularly pointed out in the claims, and the drawings show a preferred embodiment of my invention as applied to a web gravure rotary printing press, but my improvements are not necessarily restricted to any particular form or type of rotary printing press construction.

' housing 21.

Referring to the figures and more particularly to Figs. 1 and 2, the press frames II and 2 are mountedon the base l3 in spaced apart relation with the lower part of the frames H and I2 having the reentrant spaces l4 and I5 formed 5 respectively therein to allow'space for the projecting ends of the cylinder shaft when thecylinder is removed or installed. The standards I6 and I 1 preferably integral with the frames II and |2,-afford fixed socket bearing supports for 10 this cylinder. shaft as shown inFig. 1.

The press proper, preferably agweb gravure press, comprises the printing cylinder I8, the therewith coacting rubber cylinder l9 and the pressure cylinder 20 which is adapted to exert pressure on the cylinder l9. The web W is shown in Figs.'l and 2 in printing relation with the cylinders l8 and I9, and the cylinders I9 and areillustrated in their raised position with the web W out of contact with the printing cylinder l8 when the press is stopped and no printing is taking place.

The printing cylinder shaft 2| is driven from its left end 22 (Fig. 1) by the gear 23 fastened to the shaft end 22. The right end 24 carries 25 the mechanism for laterally shifting the printing-cylinder l8 relatively-to the press frames II and I2 to secure proper side registration of the cylinder. The shaft ends 22 and 24 each carry similar bushings 25 that are carried in the sleeves 2B which are journalled in the socketed portlfins of the standards l6 and I1 on which fixed bearings the cylinder shaft 2| is rotatably mounted, the width of the reentrant spaces l4 and I5 being greater than the axial length of the cylinder 33 I8 and the cylinder shaft 2|.

The means for driving the printing cylinder l8 through its shaft 2| in either direction will now be described: .On the left side of Fig. 1 is the housing 21 in which is journalled the main drive shaft 28 actuated from any suitable source of Slidably keyed at left end (Fig. 3) of the shaft 28 is the clutch gear 28 adapted to removably engage with the clutch gear 30 mounted on the sleeve 3| which encircles 5 the shaft 28 and is freely rotatable thereon. The inner end of the sleeve 3| carries the bevel pinion 32 that engages the large bevel gear 33 fast to the cross-shaft 34 journalled in the housing 21. Surrounding the sleeve 3| is the bearing collar 35 carried by the bracket plate 86 secured within the The clutch gear 29 is exteriorly grooved at 8'! in which groove 31 rides the nose 38 of the bracket 39 pinned to the slidable control rod 48 that is laterally shiftable in the bracket plate 36.

.On the right side of Fig. 3 a similar construction is shown comprising the clutch gear 4| slidably keyed to the shaft 28 which gear 4| is adapted to removably engage with the clutch gear 42 mounted on the sleeve 43 which also encircles the shaft 28 and is freely rotatable thereon. The inner end of the sleeve 43 carries the bevel pinion 44 that engages the bevel gear 33 opposite to the bevel pinion 32-. Surrounding the sleeve 43 is the bearing collar 45 carried by the bracket plate 46 secured within the housing 21. The clutch gear 4| is exteriorly grooved at 41 in which groove 41 rides the nose 48 of the bracket 49 that is pinned to the end of the control rod 48 that also slides in the bracket plate 46 as well as the plate 36.

vBy this mechanism the constantly rotating drive shaft 28 will impart a rotative movement to the cross-shaft 34 in either direction through the large bevel gear 33 depending on whether the clutch gears 29 and 38 are operatively engaged to drive the gear 33 in one direction through the bevel pinion 32, or whether the clutch gears 4| and 42 are operatively engaged to drive the gear 33 in the opposite direction through the bevel pinion 44. The lateral shifting of the control rod through the brackets 39 and 49 determines whether one set of clutch gears 29 and 38 or the other set of clutch gears 4| and 42 are in engagement with one another. When one set is disengaged its particular bevel pinion (32 or 44) is free to rotate on the shaft 28 through the gear 33 and is not driven by its set of clutch gears (29 and 38 or 4| and 42) which happen to be disengaged so as not to interfere with the predetermined direction of rotation to be imparted to the cross shaft 34.

Fastened to the cross shaft 34 is the pinion 58 which through a pair of idler gears 5| and 52 drives the pinion 53 fastened to the end of the shaft 54 journalled in the housing 2'! and press frame II in either direction as shown in Figs. 1, 2, and 3.

Pivoted to the press frames II and I2 are the two swinging arms 55 and 56 which support the end brackets 51 and 58 respectively in which is mounted a novel type of ink fountain and ink distribution devices adapted to be located on either side of the printing cylinder 8 as shown in Fig. 2 depending upon the direction of rotation of the cylinder l8 and also permits this cylinder to be exchanged from either side of the reentrant press frames without interference with the ink fountains and doctor blades by mechanism hereinafter described. The shaft 54 imparts a rotary movement by bevel gears (not shown) to the ad- J'ustable shaft 59 carrying mechanism to rotate the shaft 68 which carries the cam-operated devices for reciprocating the usual doctor blade for removing surplus ink from the printing cylinder l8 in gravure presses.

Since this ink distribution system is the subject matter of a co-pending application, it is not necessary to describe the structural details in this case. Such mechanism has a peculiar advantage in web gravure presses such as are shown herein.

Referring to Figs. 1 and 5, the inner end of the cross shaft 34 has fastened thereto the widetoothed gear 6| of similar size and teeth to, and in transverse alinement with, the gear 23 on the cylinder shaft 2|. Surrounding both the gear 23 and the gear 6| is the interiorly tooth gear sleeve 62 which is slidable on the gears 23 and, 6| and is fastened in any predetermined position on the gear 6| by the screw-pin 63. By sliding the sleeve 62 to the left in Fig. l, the gears 23 and 6| are thereby disconnected and the cylinder l8 may be removed from the press. In Fig. 1, the gears 23 and 6| are operatively connected to rotate the cylinder |8 in either direction by the mechanism within the housing 21 hereinbefore described.

Means are provided for laterally adjusting the printing cylinder l8 in the press frames and I2 best shown in Figs. 1 and 4: Mounted on the bracket 64 fastened to the frame I2 is the interiorly threaded standard 65 through which passes the screw-bolt 66 having the handle 61 fastened to its outer end. The inner end of the bolt 66 passes through the hole 68 of circular plate 69 removably held to the outer reduced end of the coupling 18 for the cylinder shaft 2| by screw-bolts Within a socket cut in the end 69 of the coupling 18, the screw-bolt I2 portion of the screwbolt 66 projects, this screw-bolt portion I2 being of smaller diameter than the screw-bolt 66 asshown in Fig. 4. The sleeved collar 13 carried by the bolt 12 divides a double set of ball bearings 14 and 15 which are held in position by the outer washers l6 and 11 within the socketed opening of the coupling 10. The lock nut 18 threaded on the inner end of the bolt 12 holds the various parts in operative position. By manipulating the handle 61 the cylinder |8 may be laterally shifted in its bearings through the coupling 18 to make the proper adjustments in either direction, and the screw-bolt 66 is locked in any predetermined position by the locking bolt 19 tapped into the standard 65 and bearing on the plate 88 above the bolt 66. The handle 8| is removably secured to the head of the locking bolt 19 as shown in Fig. 1. The coupling I8 is fastened to the end 24 of the cylinder shaft 2| by the clamping nuts 8| as shown in Fig. 1.

By these devices I have provided a ball thrust bearing for this end 24 of the cylinder shaft 2| by which the cylinder l8 may be laterally adjusted, and at the same time have provided means for disengaging the -end 24 ,of the cylinder shaft 2| within the space |5 so that the cylinder I8 may be readily removed and a different cylinder installed in the press when required.

Means are provided for removing and installing the printing cylinder I8 that are shown in Figs. 1 and 2: Such means are duplicated on either side of the press to be mounted in the standards I6 and I1, and a description of one set will suffice for both. Such standards l6 and I! have vertical slots 82 cut therein through which project the arms 83 of the levers 84 pivoted on the stub shafts 85 secured in the standards l6 and H, such arms 83 being adapted to bear on the under sides of the collars 26. The lower arms 86 of levers 84 are forked (Fig. 1), through which the threaded bars 81 pass and carry the blocks 88 that are threaded on the bars 81 while the opposite ends of the bars 81 are threaded to pass through plates 89 set in the press frames.

The tips-of the bars 81 are squared for a wrench so that the pressman may operate same from either side of the press to rotate the bars 81 and thereby rock the levers 84 on the shafts 85 in either direction. Pivoted to the press frames II and I2 in proximity to the stub shafts 85 (Fig. 2) are the runway bars 98 to'afford a track upon which the cylinder shaft ends 22 and 24 may roll-in removing or installing a cylinder in the press. l8 and its shaft ends 22 and 24 will be partly By raising the arms 82 the cylinder in Fig. 1 where such arms 82 are no longer in I contact with the collars 26 of the cylinder ends 22 and 24. I

The operations of the various different mechanisms and devices in my improved press have been described in conjunction with the separate descriptions of their structural details. However the general operations may be summarized as follows: When it is desired to install or remove a printing cylinder H3 in the press, the mechanism shown in Figs. 1 and 2 with the runway bars 90 coacting with the lever arms 84 is used either to install or remove the cylinder It! in the press frames with the reentrant spaces l4 and I5 affording sufiicient width for the shaft ends 22 and 24 and the cylinder travelling on the runway bars 90 and arms 84 to or from its bearings in the press.

Then the gear sleeve 62 is laterally shifted to engage both the gears 23 and 6|, and is fastened by the pin 63 to connect up the driving apparatus contained in the housing 21. The control rod 40 is then shifted to determine the direction of rotation of the cylinder I8, the whole constituting a reversible clutch drive that is detachably connected to the cylinder shaft end 22, such drive being laterally movable within the reentrant space l4 to free the shaft end 22 when required to remove a printing cylinder in the press. A lateral adjustment of the cylinder I8 is secured by manipulating the handle 61 as before described.

My invention, in its broader aspects, is not shaft limited to the particular construction and arrangement of the cylinders and associated mechanism as shown in the rotary web gravure printmore my improvements may be embodied in rotary printing presses of various types where it is particularly desirable to secure delicate pressure adjustments between the cylinders comprising the printing unit as well as to provide simplified means for exchanging cylinders as required.
